Abstract

The utility model provides a high-density seeding machine. A frame is provided with a seeding box, the bottom of the seeding box is provided with seed-metering openings; seed-metering shafts are arranged under the seeding box; each seed-metering shaft is provided with a seed-metering device which corresponds to the seed-metering openings; a hopper is connected under the seed-metering device; the outlet of the hopper is sequentially provided with a seed-transporting pipe and a ditching device; the bottom of the frame is provided with an earth wheel; a driving chain is connected among a chain wheel on rotating shafts of the earth wheel and chain wheels on the seed-metering shafts; the bottom of the seeding box is provided two lines of seed-metering openings; the lower part of the seeding box is correspondingly provided with the two seed-metering shafts; each seed-metering shaft is provided with the plurality of seed-metering devices which respectively correspond to one line of seed-metering openings one by one; the rotating shafts of the earth wheels at the two sides of the frame are respectively provided with a chain wheel; and the driving chain is connected among the chain wheels on each seed-metering shaft and the chain wheels on the rotating shafts of the earth wheel at one side of the frame. The high-density seeding machine can greatly improve the seeding density, further meets the seeding requirement of crops which need to be sowed with higher density, and guarantees the yield of the crops.

Description

The high-density sowing machine

Technical field

The utility model relates to a kind of sower.

Background technology

The basic structure of an existing class sower is: kind of the case of having taken a seat on the frame, the bottom of planting case has delegation's sowing port, plant the case below and be provided with a feed shaft, the seeding unit corresponding with sowing port is housed on the feed shaft, below each seeding unit, be connected to funnel, the outlet of funnel is connected to grain tube and plough successively, and land wheel is equipped with in the frame bottom, is connected with driving-chain between sprocket wheel in the land wheel rotating shaft and the sprocket wheel on the feed shaft.The shortcoming that existing this sower exists is: the density of sowing is not high enough, for some crops that need the higher density sowing, can't reach desirable sowing effect, and then can have influence on the output of crops.

The utility model content

The purpose of this utility model is to provide a kind of high-density sowing machine, and the density height that it is sowed can guarantee the high yields of crops.

For achieving the above object, the utility model adopts following scheme: the high-density sowing machine, a kind of case of having taken a seat on the frame, the bottom of planting case has sowing port, plant the case below and be provided with feed shaft, the seeding unit corresponding with sowing port is housed on the feed shaft, below seeding unit, be connected to funnel, the outlet of funnel is connected to grain tube and plough successively, land wheel is equipped with in the frame bottom, be connected with driving-chain between sprocket wheel in the land wheel rotating shaft and the sprocket wheel on the feed shaft, the bottom of kind of case has two row sowing ports, plants case below correspondence and is provided with two feed shafts, and the some seeding units that are equipped with on each feed shaft are corresponding one by one with the delegation sowing port respectively, in the land wheel rotating shaft of frame both sides a sprocket wheel is housed all, is connected with driving-chain between the sprocket wheel in the land wheel rotating shaft of sprocket wheel on each feed shaft and frame one side.

By such scheme as seen, the bottom of the utility model kind case has two row sowing ports and is provided with two feed shafts, can make the density of sowing significantly improve, and then the sowing requirement of the crops of the higher density sowing of satisfying the demand, guarantees the output of crops.

Embodiment

Further specify the utility model below in conjunction with embodiment and accompanying drawing.

Referring to Fig. 1, Fig. 2

Kind of the case 1 of having taken a seat on the frame 13 of the high-density sowing machine that the utility model provides, the bottom of planting case 1 has two row sowing port 1a, plant case 1 below correspondence and be provided with

feed shaft

14,3 two feed shafts of feed shaft, the some seeding units 5 that are equipped with on each feed shaft are corresponding one by one with the sowing port 1a of delegation respectively, below each seeding unit 5, be connected to funnel 6, the outlet of funnel 6 is connected to grain tube 7 and plough 11 successively, frame 13 two bottom sides are equipped with land wheel 8, are connected with driving-chain 4 between the sprocket wheel 10 in the land wheel rotating shaft 9 of sprocket wheel 2 on each feed shaft and frame one side.In addition, hitch frame 12 is housed on frame 14.

Referring to Fig. 1, Fig. 2, Fig. 3

The number of institute's dress seeding unit 5 is identical and relative one by one on feed shaft 13, feed shaft 3 these two feed shafts, the plough 11 that two adjacent seeding units 5 are connect on each feed shaft is the shape that staggers to be arranged, and the plough 11 residing direction unanimities that per two relative seeding units 5 are connect on two feed shafts, is arranged into row.The plough that seeding unit connect on two feed shafts is arranged by Fig. 2, rule shown in Figure 3, be from a left side among Fig. 1, be on feed shaft 13, the

feed shaft

31,3,5,7 row ploughs 11 after, be on feed shaft 13, the

feed shaft

32,4,6 row ploughs 11 preceding.
